800 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> is the fastest way to visualize metrics. It is a resource efficient, highly optimized system for collecting and visualizing any type of real-time time series data, from CPU usage, disk activity, SQL queries, API calls, web site visitors, etc.
803 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> tries to visualize the truth of <b>now</b>, in its <b>greatest detail</b>, so that you can get insights of what is happening now and what just happened, on your systems and applications.
806 To make a chart in <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b>, you just need a <b>number</b>. Just a number you can read somehow. <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> will turn this number to a real time, interactive, web chart. For collecting these numbers, it supports <a href="https://github.com/firehol/netdata/wiki/External-Plugins" target="_blank">external plugins</a>, even <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">shell</a> or <a href="https://github.com/firehol/netdata/wiki/General-Info---charts.d" target="_blank">node.js</a> plugins. Any computer program, in any language, that can print a few lines of text on its standard output, can be a netdata data collector.
809 <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> can embed charts everywhere, like this one <div data-netdata="system.cpu" data-dimensions="system" data-after="-120" data-width="25%" data-height="15px" data-chart-library="dygraph" data-dygraph-theme="sparkline" data-show-value-of-system-at="system.cpu.system.modal.1"></div> (my CPU system usage which is <span id="system.cpu.system.modal.1" style="display: inline-block; width: 40px; text-align: right;"></span>%),
810 or this one <div data-netdata="ipv4.tcppackets" data-dimensions="received" data-after="-120" data-width="25%" data-height="15px" data-chart-library="dygraph" data-dygraph-theme="sparkline" data-show-value-of-received-at="ipv4.tcppackets.received.modal.1"></div> (my IPv4 received TCP packets, which are <span id="ipv4.tcppackets.received.modal.1" style="display: inline-block; width: 60px; text-align: right;"></span>/second).
813 You can have <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> charts on your site too. Just give it a <code>div</code> and a real time chart, zoomable and draggable will appear (try it even on these tiny ones - <b>drag</b> them to pan horizontally, <b>shift + drag</b> to zoom in, on <b>chrome shift + mouse wheel</b> to zoom in/out, <b>double click</b> on them to reset them - don't be afraid of <b><a href="https://github.com/firehol/netdata/wiki" target="_blank">netdata</a></b> performance - <a href="https://github.com/firehol/netdata/wiki/Performance" target="_blank">a raspberry pi 2 can sustain 300 charts updates per second</a>!).

847 <h4>Mouse Over / Hover</h4>
848 Mouse over on a chart to show, at its legend, the values for the timestamp under the mouse (the chart will also highlight the point at the chart).
850 All the other visible charts will also show and highlight their values for the same timestamp.
854 <h4>Drag Chart Contents</h4>
855 Drag the contents of a chart to pan it horizontally.
857 All the charts will follow soon after you let the chart alone (this little delay is by design: it speeds up your browser and lets you focus on what you are exploring).
859 Once a chart is panned, auto refreshing stops for all charts. To enable it again, <b>double click</b> a panned chart.
863 <h4>Double Click</h4>
864 Double Click a chart to reset all the charts to their default auto-refreshing state.
868 <h4>SHIFT + Drag</h4>
869 While pressing the shift key, click on the contents of a chart and move the mouse to select an area, to zoom in. The other charts will follow too. Zooming is performed in two phases:
871 <li>The already loaded chart contents are zoomed (low resolution)</li>
872 <li>New data are transferred from the netdata server, to refresh the chart with possibly more detail.</li>
874 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
878 <h4>SHIFT + Mouse Wheel <small>(does not work on firefox and IE/Edge)</small></h4>
879 While pressing the shift key and the mouse pointer is over the contents of a chart, scroll the mouse wheel to zoom in or out. This kind of zooming is aligned to center below the mouse pointer. The other charts will follow too.
881 Once a chart is zoomed, auto refreshing stops for all charts. To enable it again, <b>double click</b> a zoomed chart.
885 <h4>Legend Operations</h4>
886 Click on the label or value of a dimension, will select / un-select this dimension.
888 You can press any of the SHIFT or CONTROL keys and then click on legend labels or values, to select / un-select multiple dimensions.

Normally, the dashboard starts refreshing them in parallel, but depending on the speed of your computer and the network latencies, charts start having a slight time difference. Setting this to <b>Resync</b> will attempt to re-synchronize the charts on every update. Setting it to <b>Best Effort</b> may lower the pressure on your browser and the network.</small>
